Firefox Support Forum

This has been bugging me for ages. Happened on Windows 10 and now on Windows 11.

I start watching some video on YouTube or whatever, decide it's not useful/what I want, stop playing it, close the tab or navigate away, but if my device locks, the controls for this old, discarded video, that I didn't want to watch, are on the lock screen.

I wouldn't mind if it was a video I was currently watching but it's somehow remembering the last thing I started to watch. I can see no hint anywhere else that it's still active in any way at all.

The only way to get rid seems to be to close Firfox.

This is very annoying because it seems you can't watch anything without Firefox remembering it and putting on the lock screen until the end of the session, so it could be cluttering things up all day unless I close everything and (in my case, because of prvicy settings) delete cookies and log myself out of most sites.

I've tried multiple searches but all I've found here is a post about turning off media.hardwaremediakeys.enabled but I don't actually want to do that, I just want Firefox to forget videos when I've closed the tab or navigated away from them.

Elsewhere I found a suggestion to disable dom.media.mediasession.enabled but that setting isn't found.

Any help much appreciated.

I have two questions:

1. Will WASM and JIT be turned on or not affect the operation of RLBox?

I currently have the following about:config settings set to false, I'm wondering if this will cause the RLBox to not function?

javascript.options.ion javascript.options.baselinejit javascript.options.native_regexp javascript.options.asmjs javascript.options.wasm

I hope Mozilla staff will consider listing the operating status of RLBox in about:support, so that it will be clear at a glance.

2. Enabling "security.sandbox.content.shadow-stack.enabled" will cause add-ons to not function properly.

This setting seems to have been around for a long time. Is there any progress on this? Chrome has supported this feature for quite some time.

I would be grateful if you could help clarify this and inform me of the answer.

The behavior began with fifteen to twenty crash messages appearing. After which the browser would stop responding and be unable to reach out to the internet.

Network connectivity was confirmed as I was able to access my VPN and corporate teams.

I submitted as many crash reports as I could. Eventually the crash reporter ceased to function. The message is:

Firefox had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash.

Details: expected value at line 1 column 1

Only a full reboot of the machine restored functionality but only temporarily. It returns after being put into sleep mode.

Running firefox in safe mode does not restore functionality. The behavior persists.

I am fully up to date according to firefox.

I am running a Lenovo Thinkpad Windows 11.

Firefox.exe -silent and Firefox.exe -silent -p default work, but Firefox.exe -silent -p MyProfile Not

Do it is possible to preload Firefox with a custom profile with extensions, without stay visible, to speed firefox istance open?

-os-autostart What exactly does it do?

I cannot get the print button to work in my emails. I used to be able to close Firefox and re-open and then it would work, but today that did not work. I shut down my computer completely and still it does not work. I am attaching a snip of the screen showing the print button.

I have no idea how to fix a problem that just emerged in the last hour.

I can't download file attachments sent by email. Yesterday I could. I have been using Mozilla Firefox as my browser for more than 10 years. I tried restarting my computer that didn't help.

When I'm browsing, especially when shopping, say, Amazon, eBay, or Swanson Vitamins or wherever, FF opens a new tab which remains open to the right of the left-most original tab. Of course, when I + a new tab which I want it to stay open, it opens and, again, by itself, FF closes the first tab and the latter takes over the left-most spot. And, in case of eBay, when I click on an item I want to check, it keeps on opening a new tab on the original tab. Placing the cursor on FF icon on task bar displays all the tabs. I never had things like above happen with previous issue FF. Of, course, I don't know since which FF version was stable in the way I wanted. Does anyone know how to set FF to stop taking all these unwanted actions?

Why do I only get this on firefox?? If I use any other browner I don't get it?? I sign into google and set filter to nope but this get the 'error'

If I hit the Verify your age for your Google Account I get a link to an Korean verity page I'm NOT in Korean I"m in AUSTRALIA
